biology animal tissues, morphology and anatomy of cockroach specialized cells in animals tissues and types of tissues levels of organisation in animals

  1. X - Pinworm, Y - Crow

  2. X - Mosquito, Y - Bison

  3. X - Leech, Y - Koala

  4. X - Bed bug, Y - Wildbeest

Show answer
Correct Option: A
Explanation:

Group 1 represents various members of the Phylum Platyhelminthes while Group 2 includes members of class Aves of vertebrata.

Pinworm and Crow are included in Phylum Platyhelminthes and Aves respectively.
So, the correct option is 'X - Pinworm, Y - Crow'.

Ubisch bodies are connected with the formation of?

biology animal tissues, morphology and anatomy of cockroach specialized cells in animals tissues and types of tissues levels of organisation in animals

  1. Sporopollenin

  2. Intine and pollenkitt

  3. Exine

  4. Pollenkit and pollinia

Show answer
Correct Option: C
Explanation:
When the anther is young, at the stage of sporogenous tissue, the cells of the tapetum contain numerous spherical bodies called pro-ubisch bodies. The number of pro-ubisch bodies increases by meiosis in Pollen mother cells. These pro-ubisch bodies get coated by sporopollenin and are called ubisch bodies or orbicules. These are involved in the formation of exine of the pollen grains. Thus, the correct answer is option C, Exine.

Unlike animals, plants get energy in the form of

biology animal tissues, morphology and anatomy of cockroach specialized cells in animals tissues and types of tissues levels of organisation in animals

  1. ATP

  2. Soil

  3. Roots

  4. Water

Show answer
Correct Option: A
Explanation:

Chloroplasts contain a pigment called chlorophyll. Chlorophyll is able to capture the energy from the sun. In doing this, a series of chemical reactions occur that convert the sun's energy into ATP (energy for the plant). 

Therefore, the correct answer is option A.

Show answer
Correct Option: A
Explanation:

There are four types tissues found in human body namely the muscular, epithelial, connective and nervous.

  1. Ca muscle contraction

  2. I thyroid

  3. Co energy liberation

  4. Cl nerve conduction

Show answer
Correct Option: D

Myelin sheath of nerve fibres is produced by

biology animal tissues, morphology and anatomy of cockroach types of neuron nervous tissue neural tissues

  1. Axon

  2. Connective tissue

  3. Schwann cells

  4. Neuroglia

Show answer
Correct Option: C
Explanation:
  • Myelin is a layered substance made of phospholipid, cholesterol and protein that covers the axons of the neurons.
  • It insulates the nerve impulses from the surrounding nerve fibres. 
  • It also increases the speed of impulses through nerve axons.
  • It is formed in the central nervous system by glial cells called the oligodendrocytes.
  • Whereas, in the peripheral nervous system they are produced by Schwann cells.
  • So, the correct answer is 'Schwann cells'.

Myelin sheath has layers of fat and protein

biology animal tissues, morphology and anatomy of cockroach types of neuron nervous tissue neural tissues

  1. Upto 100

  2. 10-20

  3. Two each

  4. One each

Show answer
Correct Option: A
Explanation:

  • Myelin is an insulating layer or sheath that forms around nerves, including those in the brain and spinal cord.
  •  It is made up of protein and fatty substances. 
  • This myelin sheath allows electrical impulses to transmit quickly and efficiently along the nerve cells.
  •  If myelin is damaged, these impulses slow down. Hence, the Myelin sheath has layers of fat and protein up to 100.
So, the correct answer is 'up to 100'.

The characteristic of a nerve cell that relates directly to its function is its-

  2. Flat shape.

  3. Ability to change shape.

  4. Ability to engulf bacteria.
